1921 BIRDS OP MONTANA 175 



The bird was not seen by Mr. Cameron himself, and it is another case of sight 

 identification of a bird far from its normal range. 



Carpodacus purpureus purpureus (Gmelin) 

 Purple Finch 

 Two seen in the Belt Mountains in June, 1880 (Williams, 1882a, p. 62). T 

 believe this is a mistake for Carpodacus cassini. The birds could certainly not 

 be easily separated in the field on sight alone. 



Passerherbulus lecontei (Audubon) 

 LeConte Sparrow 

 Seen at Billings, August 12, 1900 (Jones and Dawson, 1900, p. 31). While 

 this identification is probably correct, the species has never been taken in the 

 state. It is an inconspicuous species, difficult to identify in the field, and this 

 would be the extreme western limit of its range. The record had best wait for 

 verification, before being admitted. 



Cistothoms stellaris (Naumann) 

 Short-billed Marsh Wren 

 One seen at Lombard, Gallatin County, April 23, 1909 (Saunders, 1911a, 

 p. 48). While I feel .just as sure that this record is correct as when I first pub- 

 lished it, yet the bird is inconspicuous, and, in this case, it was out of its normal 

 range. Under such circumstances I do not feel justified in placing it in the 

 state list. 



Anticipating possible changes in the A. O. U. Check-List, the following bird 

 names are inserted. These are subspecies, described, but not at present accepted, 

 which have been found in Montana. These changes for the most part involve 

 alteration of names rather than the addition of species. No attempt has been 

 made to make this list complete. 



Ardea herodias treganzai. This is the form of Blue Heron occurring throughout 

 all, or nearly all, of the state (Cooke, 1913a, p. 38). 



Otocoris alpestris enthymia. Breeds throughout the eastern part of the prairie 

 region (Oberholser, 1918, p. 345). 



Molothrus ater artemisiae. This is probably the form throughout all of the state, 

 with the possible exception of the northwestern region. Dr. Bishop has identified birds 

 taken at Anaconda. 



Agelaius phoeniceus arctolegus. This form of Redwing is the one breeding over 

 all of the state except probably the southwestern and northwestern portions.
